Global environmental challenges
One of California’s biggest ports has cleaned up its fleet of 8,000 trucks.
The Port of Long Beach has cut nearly 80 percent of emissions from truck engines at the port since it started its ban of old diesel-fueled trucks. That’s roughly 200 tons less of soot — known as particulate matter — in the air at the port annually.
In 2008, the port of Long Beach, together with its sister port in Los Angeles started to green their truck fleets, targeting trucks built before 1989. Together the ports make up the busiest cargo hub in the United States.
In 2010 the ban at Long Beach ramps up to prohibit trucks from 1993 and older, plus trucks from 1994 to 2003 that have not been updated with exhaust filters to meet strict emissions standards.
At issue is a letter Palin sent to Schwarzenegger last month, asking him to veto a bill that would raise shipping container fees to pay for pollution-reduction programs at three major California ports.
